Alstroemeria named Stadutia

ABSTRACT

A new variety of Alstroemeria plant characterized by its very large blooms, the petals of which are generally of a soft red coloration highlighted by the bright yellow coloration of the central body portion of the contiguous pair of the upper ones of the inside petals, which are deeply marked by longitudinal pencil stripes which extend upwardly from the base to the petal tip. This plant is further distinguished by its continuous year around blooming habit and its vigorous, strong growth, which reaches a height of up to about 200 cm., the flowers appearing singly on the branches of an umbel formation on a flower stem length of up to 150 to 200 cm., depending upon the season.

BACKGROUND OF THE NEW PLANT

This new Alstroemeria variety originated as a seedling resulting from mycrossing of a pair of Alstroemeria plants maintained in my greenhousecollection of plants for breeding purposes. This crossing was done atAalsmeer, Holland, in 1982 with the object of producing plants havinglarge red flowers, a strong growth habit, and good wintertime flowerproduction. This particular seedling was selected fro propagationbecause it appeared to have the plant characteristics which I sought bymy breeding efforts and asexual reproduction of this selected seedlingwas done by me and under my direction at Aalsmeer with very satisfactoryresults; and under my direction, propagation of this new variety wascarried on through several successive generations, which demonstratedthat the novel characteristics would hold true from generation togeneration and appeared to be firmly fixed. The initial propagation ofthis plant was by its own roots and subsequent propagation was done bydivision of rhizomes. The present propagation of this new variety isdone at Aalsmeer, Holland, by division of rhizomes.

DESCRIPTION OF THE DRAWING

This new variety of Alstroemeria plant is illustrated by theaccompanying photographic drawing which, in full color, shows theflowers of a blooming umbel of the plant and demonstrates the flowerform and coloration, the color rendition being as nearly true as it ispossible to obtain by professional photographic procedures.
